So...what does Waze not have that you want?
I only mentioned Waze as an example. You said you never saw features, I pointed to a free one.
If turn by turn is what you need and you're not complaining about maps integration with other apps, why not just use Waze? It's free, has night mode, voice commands, poi's, traffic...etc...
Oh, I'm certainly complaining about the actual maps and its integration, but this thread isn't about the data. It's about the turn by turn and I can't see calling something that is lacking numerous basic features 'slick.'
